Ingredients:
For the Ribeye Steak:
– 2 ribeye steaks (about 1 inch thick)
– 2 tablespoons olive oil
– Salt and pepper to taste
– 2 tablespoons unsalted butter
– 2 cloves garlic, minced
– Fresh rosemary sprigs (optional)
For the Caramelized Onions:
– 3 large onions, thinly sliced
– 3 tablespoons unsalted butter
– 1 tablespoon olive oil
– 1 teaspoon sugar
– 1/2 teaspoon salt
– 1/4 teaspoon black pepper
– 1/4 cup beef broth
– 1 tablespoon fresh thyme leaves (optional)
For the Mashed Potatoes:
– 2 lbs potatoes, peeled and cubed
– 1/2 cup milk
– 4 tablespoons unsalted butter
– Salt and pepper to taste
– Fresh parsley, chopped (for garnish)
Directions:
Step 1: Cook the Potatoes 
– Place the cubed potatoes in a large pot and cover with water. Bring to a boil and cook until the potatoes are tender, about 15-20 minutes.
– Drain the potatoes and return them to the pot.
– Add the milk and butter, then mash until smooth. Season with salt and pepper to taste. Keep warm.
Step 2: Caramelize the Onions 
– In a large skillet, melt the butter and olive oil over medium heat.
– Add the sliced onions, sugar, salt, and black pepper. Cook, stirring occasionally, until the onions are caramelized and golden brown, about 25-30 minutes.
– Add the beef broth and fresh thyme (if using), and cook for an additional 5 minutes until the liquid is mostly absorbed. Remove from heat and set aside.
Step 3: Cook the Ribeye Steaks 
– Preheat your grill or a large skillet over high heat.
– Rub the ribeye steaks with olive oil and season generously with salt and pepper.
– Place the steaks on the hot grill or skillet and cook for 4-5 minutes per side for medium-rare, or until your desired level of doneness.
– For the last minute of cooking, add the butter, minced garlic, and rosemary sprigs to the pan and baste the steaks with the melted butter.
– Remove the steaks from the heat and let them rest for 5 minutes before serving.
Step 4: Serve
– Arrange a generous scoop of mashed potatoes on each serving plate.
– Place the ribeye steaks on top of the mashed potatoes and spoon the caramelized onions over the steaks.
– Garnish with chopped fresh parsley.
